clk: eswin: Add CLK_IGNORE_UNUSED to NoC clock

Browse source

The gate_noc_nsp_clk provides the essential clock source for NPU,
DSP, and PCIe subsystems. During kernel init, the clock framework
attempts to disable unused clocks when clk_ignore_unused kernel
parameter is not set.
However, gate_noc_nsp_clk is required to remain enabled for these
critical subsystems to function properly, causing PCIe boot failures
when auto-disabled.

Add CLK_IGNORE_UNUSED flag to gate_noc_nsp_clk to ensure it stays
enabled even when clk_ignore_unused is not specified in kernel
command line.
